JOHN LEWIS MILTON, OF LOUISVILLE, KENTUCKY.

ELECTRICAL SYSTEM.

" Specification of Letters Patent.

. Patented Feb. 7, 1922.

To all whom it may concern:

Be it known that I, JoHN LEWIS MILTON, a citizen of the United States, residing in Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Electrical Systems, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an electrical generating and distributing system and rtains particularly to the simplification 0 the construction of such an apparatus, together with the production of the apparatus, the parts of which are so correlated as to provide a mechanism of relatively high magnetic and electrical efiiciency, as an entirety? Figure 1 is a vertical longitudinal section of my inductor alternator generator and high tension current distribut'j g apparatus. Fig. 2 is a cross sectional view-bf Fig. 1 on the line B-'B.,

In the drawings 1 indicates the base, preferably of magnetic material,- for the generating apparatus, this base piece 1 has cast integral with it, in non-magnetic material, polar shoes or portions of the opposite polarity which are spaced axially "of the.

rotor base and which register withthe yoke carrying the generating windings.

I have shown the base 1 with extensions 22 of the same material as the base for carrying the bearing end pieces 33 which in turn support the ball-bearings 44 of the rotor with its shaft 6 substantially the same as in my United States patent appli-' cation Serial Number 263,752 filed November 22nd. 1918.

The other pole is constructed in sections 33910 so that the main body 33 can be removed without disturbing the polar shoes or extremities 9-10 which are secured to the pole 1 by non-magnetic mate;

rial 11 preferably of die cast metal,

It is at once apparent that an 1ntegral polar structure is formed in which the polar faces are definitely located with reference to the axis of the inductor-generator, independent of other supporting members. It will also be noted that the coil 37 and the pole yoke 33 can be assembled to the base of the machine without disturbing the polar structure, in which the rotor, bearin and supports are to be first assembled. ii) the yoke 33 are attached magnetic blocks 1314 preferably by rivets 15. The yoke with its blocks is held to the main or polar structure by non-magnetic end plates 1617 as shown. i

The rotor arms are so placed with reference to each other as to make the generated electric current cycles occur at dissymmetrical time periods. This featureis of particular value when the ignition system is used on V type engines. The lobes of the rotor, the formation of the stator, the

arrangement of the timer, distributor, windings and magnets are all susceptible of many variations as are well known in the art without departing from the spirit of the invention and can be arranged for use in connection with practically all types of internal combustion engines.

In Figs. 1 and 2 the magnetism is shifted in and out of arms 33 and 33 as the rotor arms 35-36 rotate and establish paths of low magnetic reluctance between arms 33" and 33 and the base 1 of opposite polarity. The fine and, coarse windings shown in coil 37 are completed as a unit and slipped on to the yoke as shown. .38 indicates a timer cover under which asuitable timer is provided for a two cylinder V type motor cycle engine. I

Many variations and combinations of this invention are possible and I do not limit myself to the forms shown and described in detail.

What I claim as new is 1. A magneto frame unit having a bore for a rotor and composed of magnetlc and nonmagnetic portions, said unit having on 0pposite sides of the axis of the bore pole faces which magnets are adapted to engage, and having on the same side of the axis said polar members being-spaced axially of the rotor bore.

2. A magneto frame unit having a bore for a rotor and composed of magnetic and non-magnetic portions, said unit having on opposite sides of the axis of. the bore pole of the bore a pair of polar members, and

faces which magnets are adapted to engage, and having on. the same side of the axis of the bore a pair of polar members, there being an open space between said polar members, and said polar members being spaced axially of the rotor bore.

3; A magneto frame having a bore for a rotor and formed in an integral or unitary structure from magnetic and non-magnetic material, the magnetic material part having two pole faces on opposite sides of the axis of the bore, and including also two separated polar members arranged on the same side of said axis, and said polar exfiremities being spaced axially of the rotor ore.

4. A magneto frame unit having a rotor bore and composed of several parts of magnetic material and non-magnetic material separating and holding said first-named parts in fixed relation to one another, said unit having on opposite sides flat pole faces and having at the top a pair of polar members constituting two of said parts of magnetic material, and said polar members being spaced axially of the rotor-bore.

5. A magneto frame unit having a rotor bore and composed of a pluralityof parts of magnetic material and non-magnetic material separating and holding said firstnamed parts in fixed relation to one another, saidunit having on opposite sides and disposed in parallel planes a pair of flat faces, with which magnets may engage, and also having two of said parts of magnetic material in the form of polar mem bers arranged on one sideof the unit and having other faces in a plane substantially at right angles to the plane of the firstnamed faces, and said polar members being spaced axially of the rotor bore.

6. A magneto frame unit having a rotor bore and composed of magnetic and nonmagnetic material formed into an integral structure, the frame having on opposite sides a pair of parallel pole faces formed on part of said magnetic material and provided on one side between saidfaces with a pair of polar members constituting other portions of said magnetic material, and said polar members being spaced axially of the rotor bore.

7. A magneto frame unit having a rotor bore and composed of magnetic and nonmagnetic material formed into an integral structure, the .frame having on opposite sides a pair of parallel pole faces formed on part of said magnetic material and provided on one side between said faces with a pair of polar members constituting other portions of said magnetic material, the inner faces of said polar members conforming to the curvature of the bore, and said polar members being spaced axially of the rotor bore.

8. A magneto having a rotor, a frame v unit provided with a bore for the rotor, magnets and a coil carrying core, the frame unit being composed of magnetic'and non-- JOHN LEWIS MILTON.
